[LittleBadger]

8 week old Think different suddenly in trouble.
leaves turning yellow with green veins and brown spots/patches.
plant is growing vigorously and flower buds are fattening up fast!
this is in soil with chemical nutrients.
switched to flowering nutes 5 days ago.

Hmmm...
some problem with photo !?!?

Pic not working. You just switched to bloom nutes at 8 weeks?

 

[LittleBadger]

yes - nearer 7 weeks when i switched.
i read here to switch when vertical growth stops.

I'm going to move this thread to the Cannabis Infirmary section so you'll get more eyes and a faster diagnosis, LB. :smokebuds:

Top growing, and bottom yellowing, slowly moving up the plant?
